一、蜗轮蜗杆采用先进齿形是提高曳引机效率的途径蜗杆齿形从工艺性与效率上比较,我推荐天津蜗轮减速机厂生产的系列减速机所选用的圆弧齿圆柱蜗杆齿形,该齿形具有以下特点:1.由于蜗轮和蜗杆是凸凹啮合,在啮合区的绝大部分综合曲率半径大,因而降低了齿面应力,增强了齿面强度,提高了承载能力(比阿基米德蜗杆高50%)。见图1。 First, the use of advanced worm gear worm is to improve the efficiency of traction machine worm tooth form from the technical and efficiency comparison, I recommend the Tianjin worm gear reducer plant series of gear reducer selected cylindrical worm gear tooth profile, The tooth profile has the following characteristics: 1. Since the worm gear and the worm screw mesh with each other, most of the integrated radius of curvature in the meshing area is large, thus reducing the tooth surface stress, enhancing the tooth surface strength and improving the bearing capacity (Biagi Mead worm is 50% higher. see picture 1.
